What is a helpful step when bleeding a fuel system?

Ensuring the fuel filters and strainers are full is a crucial step when bleeding a fuel system. This step is vital because it helps to make sure that there are no air pockets or contamination within the fuel system, which could hinder proper operation. A full fuel filter or strainer indicates that fuel is available without interruptions, allowing for a smooth flow through the system.

If the filters and strainers are not full, air can enter the fuel lines, leading to operation issues or engine stalling. By making sure they are full before attempting to bleed the system, you set up the conditions for an effective and efficient process, facilitating the removal of air and ensuring proper fuel delivery when the system is brought back online. This also helps to ensure the longevity and reliability of the engine's performance.
